In taxonomy, Ruegeria is a genus of the Rhodobacteraceae.[1] This genus was formerly known as the marine Agrobacterium before they were reclassified in 1998. It bears in fact the name of Hans-Jürgen Rüger, a German microbiologist, for his contribution to the taxonomy of marine species of Agrobacterium.[2]
The genus is characterised by members who are:[3]
Phylogenetically it is very close to the genus Silicibacter, but the two remain separate species due to phenotypic differences — two species for which this is problematic are Ruegeria lacuscaerulensis and Ruegeria pomeroyi.[4][5]
Two species that have been removed from the genus are Marinovum algicola (Ruegeria algicola) and Thalassobius gelatinovorus (Ruegeria gelatinovora).[6][and refs therein]
Highly abundant bacterial small RNAs have been shown to be present in the bacteria subjected to chronic nutrient limitation. In Ruegeria pomeroyi RNAseq analysis identified 99 putative sRNAs.[7] The bacterial sRNAs regulatory mechanisms are typically based on direct RNA-RNA interaction with a target mRNA.[8] The target gene groups identified by Rivers et al. were genes involved in transport, genes mediating cell-cell interactions, signal transduction and transcriptional regulation.
